摘要： Systems and methods of generating timing triggers to determine timing resolutions of gamma events for nuclear imaging includes receiving a pulse signature representing a succession of triggers associated with a photomultiplier. When a number of triggers occurring within a predetermined time interval matches a predetermined number, an event trigger can be initiated. A delayed version of the pulse signature can be generated and compared to a predetermined timing trigger level. When the delayed version matches the predetermined timing trigger level, a timing trigger can be generated. Based on the timing trigger level, the timing trigger can be generated at the pulse of the delayed version that corresponds to the first photoelectron of a gamma event. The timing trigger can correspond to a timestamp for the first photoelectron so that a data acquisition system can identify the pulse from which to acquire energy information to generate a nuclear image.

摘要： A system and method are provided for determining the onset of gamma interactions for positron emission tomography (PET) imaging more accurately than with existing techniques. The timing of a sequence of primary trigger events is obtained and used to determine a weighted combination, which mixes the timing information from the various primary trigger events to compute an overall event trigger timing with improved time resolution. Numerical simulations demonstrate that the invention improves time resolution by approximately 10% over state-of-the-art methods. This improved time resolution directly benefits the imaging performance of the PET scanner, especially in time-of-flight (TOF) mode, where a high time resolution directly translates to a reduction in image noise at the same dose—or, alternatively, a reduction of dose to the patient or scan time for the same image quality.

摘要： The invention relates to an organic light-emitting diode (OLED) having an improved lifetime and improved transport of negative charge carriers. The organic light-emitting diode is based on an organic semiconductor material, in which the transport of negative charge carriers and stability with respect to reduction is achieved with triarylated Lewis acid units, in particular perarylated borane units. This leads to an improved lifetime of the emission layer which in turn increases the lifetime of the component and eliminates the need for correcting brightness during operation. Furthermore, the invention relates to organic light-emitting diodes in which the position of the emission zone in the emitter layer and the color of the emission can be influenced in a targeted manner through triarylated Lewis acids such as perarylated borane units.

摘要： A silicon photomultiplier has a silicon chip with an array of microcells. The microcells form photon-sensitive active areas, each surrounded by photon-insensitive inactive areas. At least one elevated, three-dimensional light concentrating structure is located directly on top of the silicon chip within an inactive area and configured such that photons that would have hit an inactive area are redirected towards an active area. The light concentrating structure does lead to increased detection efficiency. The SiPM is usable in areas like medical imaging (e.g. PET, SPECT, CT and other X-ray detectors) as well as astrophysics, high-energy physics and other analytics applications.

Each of the plurality of cell cluster outputs is connected to one of a plurality of cluster readout circuits, each of which includes an analog to digital converter that converts an analog representation of the total energy received by a photon detection cell cluster to a digital energy signal. A SiPM Pixel reader circuit is connected to the plurality of cluster readout circuits and configured to generate an overall pixel output by digital processing the plurality of digital energy signals received from the plurality of photon detection cell clusters by way of the plurality of cluster readout circuits. The SIPM pixel reader circuit also receives digital signals representative of timing triggers and the total energy received by a specific photon detection cell cluster and generates an overall SiPM energy signal and overall timing trigger in response to the signals received from the plurality of cluster readout circuits.
